The invention still further relates to the computer program that is used to format storage medium.
Background technology
The format optical record carrier can be from the national information technical standard council (NCITS): working draft, T10/1675-D, revised edition 1, on October 11st, 2004, learn in " infotech-multimedia order MMC-5 (INFORMATION TECHNOLOGY-Multimedia CommandsMMC-5) " (in this document, also being called MMC-5) this draft proposes.In MMC-5, require this DVD+RW dish of format before user data can be written into the DVD+RW dish.Can be according to providing formatting command as the known protocol that defines among the MMC-5.Form user data area according to this form, its front is to import (lead-in) control zone.After the data field of following described importing control zone, can write down another control zone in the end boundaries of described data field, this another control zone is often referred to as derivation (lead-out).
According to described formatting command, have to be recorded in the control zone on the equivalent layer.According to the chapters and sections 4.4.8.3 of relevant DVD+RW basic format, initial with respect to record carrier, the MMC-5 definition: the data field is a user's space, should come addressing according to LBA (Logical Block Addressing) (according to the known LBA of DVD-ROM).The physical address of DVD+RW is identical to the mapping of logical address and DVD-ROM's: when physical sector number (according to DVD-ROM known PSN) when representing the sector in the data field, and its LBA=PSN-030000h.In addition, MMC-5 has described format in the chapters and sections 6.5 about format unit command.Described format unit command changes into addressable logical block according to the option that defines in the MMC-5 agreement with medium format.A formative specific examples that is known as the DVD+RW basic formatization has been described in chapters and sections 6.5.3.4.12.In this order, the amount field of piece will be set to or by reading the value that format capacities command is returned, perhaps be set to FFFFFFFFh.The described active volume of reading format capacities command detection medium.Because this set, storage medium formats with its maximum available to the predetermined mapping of physical address by the applied logic address.
Currently developing recordable multi layer record carrier.On multi layer record carrier, each layer all has its annular data zone, and these annular data zone can constitute single logical data storage space together.For example on dual-layer record carrier, on ground floor, annular data zone is initial with Lead-In Area, and terminates with the intermediate controlled district.Then, the second layer is initial with the intermediate controlled district, and to derive the control zone termination.
Yet this known formatting method is inflexible, does not allow to make the multilayer carrier to be suitable for the purposes of any desired.Particularly, MMC-5 does not provide any concrete grammar of formatting multi-layer storage media.
Summary of the invention
Therefore, an object of the present invention is to provide the formatting system that allows formatting multi-layer storage media.
According to a first aspect of the invention, utilize the equipment of describing as the introductory song section that is used for recorded information to realize this purpose, formatting mechanism is arranged to come formatting multi-layer storage media by second control zone of second radial position on first control zone of writing down first radial position on this layer on each layer of multilayer storage medium and this layer, so that between these control zones, form the annular data zone of selected size, if and format size is less than the maximum available dimensions on the storage medium, so also be used on each of described layer corresponding first and second control zones, location in basic first and second radial positions that equate, in order to forming radially corresponding annular data zone, so that format size equals each the summation of selected size of these annular data zone.
According to a second aspect of the invention, utilize as the method that is used to format storage medium of introductory song section description realizes this purpose, under the situation of multilayer storage medium, described format is included in each layer of multilayer storage medium and goes up first control zone of last first radial position of this layer of record and second control zone of last second radial position of this layer, so that between these control zones, form the annular data zone of selected size, if and format size is less than the maximum available dimensions on the storage medium, so also be used on each of described layer corresponding first and second control zones, location in basic first and second radial positions that equate, in order to forming radially corresponding annular data zone, so that format size equals each the summation of selected size of these annular data zone.
The effect of these measures is, but has made formatting command effective for the multilayer storage medium of for example rewriting type double-layer CD.First and second control zones have constituted the border of annular data zone on each layer.Owing on the different layers of multilayer storage medium described first and second control zones are being positioned in the equal radial position, so the annular data zone on the different layers is being space coincidence in the radial direction.If format size is less than the maximum available dimensions on the storage medium, the advantage that has of this set of annular data zone has been to reduce scanner head in the demand of advancing in the radial direction so, and this has improved the speed of record and reading of data when jumping to different layers.
The present invention is also based on following understanding.Traditionally, during the formatted record carrier, described annular data zone is formatted into continuous zone, has the derivation control zone endways.For example according to MMC-5, as above explanation, that format and map addresses cause maximum sized physics to link to each other is regional.The inventor has been found that by in the record controls district, inside and outside radial boundary place of each recording layer of record carrier, the known procedure of this format individual layer record carrier can be used for multi layer record carrier.Yet they also find, if format size less than the maximum available dimensions on the storage medium, this set can cause the setting that the data field is not fit to so so.By using traditional format process, ground floor can have its full-size then, and layer subsequently can be less than full-size to meet the requirements of total format size.Positioning control district in the space coincidence radial position can obtain the annular data zone that radial dimension equates and have corresponding radial position substantially.Therefore scanner head can jump at interlayer easily and apace.
The inventor has been noted that known read-only type multi layer record carrier is by making for the compression molding techniques of each layer use master.When in order to create master data being handled, the data total amount that will be stored on the record carrier is known.Therefore, for the reason of making, usually, the data total amount creates described master by being subdivided into equal part roughly.Yet, the process of this segmentation given data total amount can not with compare for the format of the blank record carrier that will write down with the unknown data amount.General knowledge is always to format the maximum available data capacity of such dish to them.The inventor at first finds, by can being useful with total the write down size that formats the restricting data district before in all data.Subsequently, according to the present invention, by such as positioning control district, suggestion ground realize this restriction, particularly before data to be recorded are known, realize this restriction.
At last, the inventor has been noted that some recording units that are applicable to the double-deck storage medium of write-once appear on the market.Yet such register is postponed till the record of control zone after the record of data.Thereby do not carry out the specific formatization of carrying out at multi layer record carrier of current suggestion; Especially, such equipment is not to be arranged for the control zone that record pre-determines every layer of selected size.Therefore, although advise that mainly but this novelty formatting procedure is used for the rewriting type storage medium, it also can be used for the write-once type multi layer record carrier, carries out initial setting up with the selected size to each layer.
In an embodiment of described equipment, formatting mechanism is arranged for the quantity of the layer of determining the multilayer storage medium, and is used for determining selected size by removing format size with the described quantity of layer.This advantage that has is, the space total amount of requirement is indicated by the format parameter that is used to be provided with every layer selected size.
In an embodiment of described equipment, formatting mechanism is arranged for the quantity of obtaining piece from the formatting command as dimensional parameters, and is used for determining selected size by the described quantity that selected size equals piece is set.This advantage that has is that described dimensional parameters is used to every layer size is set, and total format size is determined by the quantity of layer and in conjunction with dimensional parameters.Therefore, the user can be provided with and will be applied to the selected size of each layer.
Other preferred embodiments of method and apparatus according to the invention provide in other claim.

When the given format order, this equipment can for example import the formatting procedure that the control zone begins reality by writing.Whether this order and implicit process thereof must finish the value that depends on the position of IMMED shown in Fig. 4 immediately.If the IMMED position is zero, will to take ata bus formatted fully up to described importing for driver so.
Generally speaking, blank panel must format, so that the DVD-ROM driver can be read it.According to existing MMC-5, formatting command only allows single format size, i.e. Zui Da size.According to the present invention, a solution is provided, make formatting command can allow large-scale different size.Should be noted that described solution can use known formatting command, for example above referring to figs. 2 to the 5 MMC-5 examples of describing.
Formatting command as shown in Figure 5 comprises the dimensional parameters 51 of indicating format size.In recording unit 12, described formatting unit 16 is finished the following function that is used to carry out formatting command.For formatting multi-layer storage media, each layer of following record.First control zone is write down in first radial position place on described layer, and second control zone is write down in second radial position place on described layer.Form annular data zone between two control zones, it has the selected size of being determined by described radial position.Should be noted that the so-called Lead-In Area in first control zone on the ground floor, and the so-called leading-out zone in last control zone on the final layer.Other districts that finish (end) or beginning (start) floor in the centre can be called the middle layer.Total format size is the summation that each layer gone up the data field size in the independent stratum.
If format size is less than the maximum available dimensions on the storage medium, the position of so following definite control zone.At first determine every layer of selected size that goes up the data field.Subsequently, provide first and second control zones on border, data field to form selected size by location on every layer.Especially, locate first control zone, locate second control zone in basic second radial position place that equates in basic first radial position place that equates.Thereby formed radially corresponding annular data zone.Selected size is set, makes format size equal in the annular data zone the selected size sum of each.
In the embodiment at the multilayer storage medium, this medium can have track pattern opposite on adjacent layer, is called contrary orbital path record carrier.For example, the dual layer discs with contrary orbital path can be called the Lead-In Area that has on the ground floor of L0 as being in first control zone of smallest radial position, but this smallest radial position constitutes the inner physical boundary of posting field.Be called on the second layer of L1, first control zone that is called leading-out zone is recorded in the corresponding radial position that is in inner physical boundary, and it stops the data field now on L1.Selected size, promptly half of total format size is determined, and is used for determining the position of last second control zone of L0, and this second control zone is called the L0 mesozone.Because the selected size that requires is less than full-size, the L0 mesozone is not in the physics outer boundary of posting field, but the radial position that mediates.On L1, write down another mesozone in corresponding second radial position place, i.e. the L1 mesozone.
Fig. 6 has represented the format function of register system.Described format function can be finished in the programmable unit based on software program of for example PC or microprocessor.Replacedly, described format function can embedding ratio such as the recording unit of CD drive in.At first, at initial 61 places, supposing the system is ready.Install in 62 in step, storage medium 11 is added into, and for example is inserted into or is activated, and the unit that is used for the physics accessible storage medium is activated.Receive in 63 in step, can receive order by interface, this interface is user interface or to the interface of PC system for example.Suppose to have received formatting command.Formatting command comprises format size indication, for example the indication that will format this storage medium with storage medium maximum sized 80% or specific dimensions.Then, determine in the capacity 64, for example the active volume of the physical disks parameter detecting record carrier that obtains according to the indicator (for example bar code) on record carrier or record carrier or the box in step.Calculate in 65 in step, determine the size that each layer data district requires according to the format size of each floor and the quantity of physical data capacity and floor.The size that requires in logic of data field also is used to determine control zone physical location in the radial direction.As everyone knows, actual radial position can be based on the servo-information on the blank record carrier Already in, for example pre-groove or servo pattern.Then, in step record 66, on ground floor, write first and second control zones.In one deck 67, if must write other layers, then step record 66 is returned in decision under step.If not, finish format at ready 68 places of point.Should be noted that the order of writing each control zone replacedly can be set at first write down first control zone on each layer, writes down second control zone on each layer subsequently.A kind of order in back in practice can be faster than first order, because it is relatively slow to move radially writing head between inside and outside border, and jumps very fast relatively at interlayer.
In one embodiment, the quantity NL of the layer of the definite multilayer storage medium that has been added into of formatting system.Subsequently, in order to determine selected size SS, format size derives from the formatting command that receives, and for example the format parameter 51 from the indication format size derives.Then, selected size is calculated except that format size by the described quantity NL with layer.For example, the format size quantity NB that can be used as piece provides.Then, selected size is determined by the quantity of removing piece with the quantity of layer:
SS＝NB/NL
In one embodiment, formatting system obtains the quantity NB of piece from the formatting command as dimensional parameters.The described quantity NB of piece can directly indicate the selected size of requirement, and the described quantity NB that total thus format size equals piece multiply by the quantity NL of the layer for the treatment of formative storage medium.Therefore, the selected quantity NB that is sized to equal piece.
In one embodiment, step receive 63 be configured to receive have ground floor (L0) and the second layer (L1), as the double-layer CD of multilayer storage medium.It is dimensional parameters that formatting command provides the quantity NB of piece.Subsequently, step is calculated quantity (NB) that the 65 selected sizes (L0size) that ground floor is set equal piece divided by 2:
L0size＝NB/2
Therefore, the quantity NB of piece infers the selected size of L0, also infers the selected size of L1, and it equates.
The direct transmission that should be noted that existing format function can cause being fixed on the rewritable disk only a kind of formatting system of format size, the size that described only a kind of format size is promptly maximum.Allow different size, make the user can utilize the advantage of dirigibility, thereby create the dish that is used for different application.In addition, half that L0size is calculated to be total dish size is the wise mode of utilizing the parameter of standard format command, and this has prevented to introduce new and dimensional parameters difficulty.
Fig. 7 has represented formatted record carrier.This figure has schematically shown record carrier 11, and wherein center pit 10 provides and has been used for radial oriented at the recording unit rotary recording carrier.Represented the first recording layer L0 and the second recording layer L1 among the figure, can be from identical entrance side by focusing on the described first recording layer L0 of light beam 81 accesses and the second recording layer L1 that equivalent layer comes self-scanning 80.But each layer has internally physical diameter to the posting field 70 of outer physical diameter, and described diameter needles defines corresponding storage media types and will be covered by any recording unit.As discussed above with described record carrier formatization to the total format size that is lower than available maximum data capacity.In addition, extended to as arrow 701 indicated smallest radial positions and write first control zone 71 that for example imports at the inner boundary of L0.The L1 inner boundary in identical smallest radial position has write the first other control zone of for example deriving.On L0, extended to as arrow 702 indicated intermediate radial position and write second control zone 73, i.e. mesozone, top, and on L1, write other mesozone 74 in identical radial position.For example, this can cause carrying out formative dish with 60% of maximum data capacity.
Although the present invention mainly is illustrated by the embodiment that uses the DVD+RW double-layer CD, but the present invention also is suitable for other multi layer record carrier, the information storage system of rectangular optical cards, magnetooptical disc, high density (blue light) dish or any other type for example, but this system has carry out formative recording layer in annulus.Especially, Ceng quantity can also be greater than 2.Then, provide the corresponding control zone of beginning and end boundary can be positioned on each layer, so that the data field is a space coincidence for piling up of layer.
